What is Prostate Cancer and What Causes it? (Definition)
Prostate cancer is a cancer of the prostate gland. The prostate is a small walnut-shaped gland which lies just below the bladder in front of the rectum and produces the seminal fluid that nourishes and transports sperm. Prostate cancer is the second-leading cause of cancer death for men in the United States and about 1 in 7 will be diagnosed with it in their lifetime.
Almost all prostate cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids). Prostate cancer is for the most part a slow progressing disease. Many men with this form of cancer often die of old age or other conditions, without ever knowing they had prostate cancer. Knowing the stage of prostate cancer or how much it has spread will help determine treatment.
As a man ages, the prostate tends to increase in size. This can cause the urethra to narrow and decrease urine flow. This is called benign prostatic hyperplasia, and it is not the same as prostate cancer.
According to the CDC, certain genes (passed from parent to child) that you inherited from your parents may affect your prostate cancer risk. Currently, no single gene is sure to raise or lower your risk of getting prostate cancer. However, a man with a father, brother, or son who has had prostate cancer is two to three times more likely to develop the disease himself.
Prostate Cancer Symptoms
Different people have different symptoms for prostate cancer. In its early stages, some men do not experience any symptoms. Some advanced symptoms of prostate cancer include trouble urinating, weak urine flow, pain or burning while urinating, frequent urination, blood in the urine or semen, dull pain or discomfort in the pelvic area, erectile dysfunction, painful ejaculation, pain in the lower back, hips or upper thighs, loss of appetite and loss of weight.
If you feel you are at risk of developing prostate cancer or have experienced symptoms, talk with your doctor.
What is a PSA Test?
Prostate specific antigen (PSA) test: Measures the level of PSA in the blood. PSA is a substance made by the prostate. The levels of PSA in the blood can be higher in men who have prostate cancer. The PSA level may also be elevated in other conditions that affect the prostate.
